For those unaware, Microsoft's latest Spartan browser is based on the company's new rendering engine named Edge, which is the forked version of Internet Explorer's Trident engine. At the time of Microsoft's 'The Next Chapter' event, we saw few Spartan features including Cortana integration, reading list with synchronisation, and web page annotation. However, a lot still remains to be seen and heard about the browser, which is yet to become a part of the Windows 10 Preview Builds.
